The switch 24 is connected to the battery in series by a lead wire (not shown) and acts as an alternative to the switch provided in the cap 12 portion in the above-mentioned embodiment. Therefore, when the switch 24 is turned on, the function as cordless headphones is activated.

In the headphone auto power mechanism configured as described above, when the user wears the headphone 1 on the head with the headband 2, the housing 4 is pushed in the direction of the arrow D via the ear pad 5. When this movement exceeds a certain level, the actuator 23 of the switch 24 comes into contact with the protrusion 22. Then, when the headphones 1 are completely attached to the head, the actuator 23 is strongly pushed by the protrusion 22, so that the switch 24 is reliably turned on. When the headphones 1 are removed from the head, the force pushing the housing 4 is lost, so the spring plate 21 returns the housing 4 in the direction opposite to the arrow D, so that the actuator 23 of the switch 24 is separated from the protrusion 22. Switch 24 is turned off. With such a function, the switch 24 is automatically turned on and off regardless of the user's attention, so that wasteful consumption of the battery can be prevented.

The structure of the battery storage unit and the slide mechanism of the head pad described above are both halves on one side of the headphones shown in FIG. 5, but also in the other half, the directions are symmetrical. There is no structural change. In the embodiment shown in FIGS. 1 and 2, the structure of the part where the locking part formed at the tip of the band locks in the battery storage part is not limited to that shown in the drawing, and other structures may be used. It may be. Further, in the embodiment shown in FIG. 9, the housing is rotatably attached to the lower end of the front hanger and the switch is provided inside the housing. However, the position of the switch and the operating mechanism are not limited to this. It is not something that can be done. The point is that the headphones are automatically switched on when the user wears them on the head, and switched off when removed from the head.
